Why can shelf life be hard to predict?

• A. Shelf life is fixed by the manufacturer.
• B. Shelf life is shorter if you know the brand.
• C. Shelf life can vary based on storage conditions and product type.
• D. Shelf life is longer if you know the brand.

Answer: (C)

Shelf life is hard to predict because how long a product lasts depends on chemical stability within its formulation and on how it’s stored. The active ingredient can degrade at different rates depending on storage temperature, humidity, and light exposure, and some formulations protect the ingredients better than others. Packaging, the presence of stabilizers, and whether the product is a concentrate or ready-to-use can all influence how quickly degradation occurs. Real-world storage conditions vary widely, so the same product can behave differently in different environments. Because of this variability in storage conditions and product type, predicting an exact shelf life isn’t straightforward.
